There was a different issue with his project. He had 13 instances of same object with some variables. And while saving to webstorage he did not specify what he want to save.

Webstorage-->Set Local Key"GunUnlock" To TurretGun_BttnFam.UnlockedGun [/code:yup8lgsg]
1 instance of [b]TurretGun_BttnFam[/b] had [i]UnlockedGun[/i] variable set to [b]1[/b] but other 12 instances had [i]UnlockedGun[/i] variable set to [b]0[/b]
So this one event was "confused" what to save.
